This application is a division of m application for Letters Patent of the I nited States, filed December 15, 1919, Serial Numher 344.962, and renewed November 16, 1925, entitled Improvements in plows and which on the 9th day of November 1926 matured into Patent Number 1,606,132.

It relates particularly to a combination and correlation of parts by which crank axles carried by the supporting wheels at opposite sides of the implementwill be caused simul taneously to more pivotally with relation to the frame of the implement to therebycause simultaneous movement of the said wheels in one direction to lower the frame and ground working elements from transport posltlon to working position and in the opposite direc tion to raise said frame and ground working elements from working position to transport position, and which combination and correlation also will apply power to an element which controls corresponding movements of a supporting wheel at the rear end of the implement.

One of the important purposes of the present invention is to provide a means 0. the kind referred to which is particularly characterized by the capability of an adjustment of one of the crank axles relatively to the other, into any one of a plurality of selected positions. Another of the important purposes of the invention is to provide a combination and correlation of parts in which power applied to one of the supporting wheels to raise or lower the frame into and from transport position will be transmitted correspondinglyto the other wheels through a mechanism which permits adjustment of the wheels at one side of the element to thereby variably determine the depth of penetration of the ground working elements and additionally permits an adjustment of the :.-=upporting wheel at the other side to level the frame.

These several purposes, and others which will be apparent to those skilled in the art from the following description of my invention, are secured from the construction illustrated in the accompanying drawings, and in which drawings Fig. 1 is a perspective view of a power lift gang plow embodying the present improvements viewed from the furrow side.

Fig. 2 is a detail perspective view particuhas larly intended to show the connection between the furrow wheel axle and the land wheel axle, thisview beingttaken fromthe side of the implement opposite to that. which it is seen in Fig. 1. y

Similar characters of reference denote corresponding parts in both of the views.

The drawings illustrate the invention in its application to a power lift gang plow and will be particularly describedwith reference to its said application without, however, intending to restrict it exclusively to such application. It may be embodied in tillage implements other than gang lows and certain of its novel features an combinations may be usefully employed intillage im lements whichdo not include any power ift mechanism for raising the frame and ground working element or. elements from ground working position to transport position and for lowering said frame and element or elements from transport position to ground working position. It should be understood thatthe term power lift mechanism herein employed has reference to those mechanisms which include a clutch which is under control of the operator and which, when its driving and driven members are locked together, operate to cause the ground working element or elements to be raised and lowered by power derived from one of the ground engaging wheels of the implement. These mechanisms usually operate by successive half-revolutions to raise and lower the ground working element, respectively, and include means by which the driving and driven members are unlocked from each other at the end of each half-revolution.

Such power lift mechanisms are well known.

yet I would have it understood that its detail construction exemplified in the drawings particular advanta es in connectionwith a til age implement having a power lift mechanism since it very efficiently and effectively co-acts with said mechanism in permitting adji'lstment of the ground workin element or elements to variably regulate t e depth of Divided penetration of said element or elements into the soil and in permitting adjustment of one side of the frame relatively to the other for leveling purposes, and finally as a means for transmitting pivotal movement from the means to which the power for raising and lowering the frame and ground working element or elements is applied by the power lift mechanism to the corresponding axle at the other side of the implement and to an element which controls corresponding movement of the supporting wheel at the opposite end of the implement. For these reasons certain of the appended claims are based upon a tillage implement of the power-lift type including novel combinations and correlations of elements of the power lift mechanism and elements which form connections between the axles and which permit relative adjustments.

A detail explanation of the particular em bodiment illustrated by way of example in the accompanying drawings, follows The illustrated frame comprises twosubstantially parallel longitudinal beams 10, 10 tied together near their rear ends by a transverse connecting element 11 and at their front ends by a transverse member 11 and corner brackets ll. Each beam has a downwardly bent rear end to which is attached a plow body 12 of the single mold-board type. It will be understood, however, that any suitable construction of frame and that any tillage or ground working element of a kind suitable for use with those parts which constitute the present invention are contem plated to be within the spirit of the invention.

A, B, and C designate the land and furrow wheels which. support the implement, A being the front furrow wheel, B the land side wheel and C the rear furrow wheel. The front furrow wheel A and the land side wheel B are lnounted on separate crank axles whose journaled portions, marked M and 18, respectively, extend transversely of the frame, from side to side of the latter and one immediately adjacent the other. These journaled portions are mounted in bearings 15 carried by the beams 10, 10. The crank portion of the axle of the furrow wheel Ais designated l6 and said wheel is mounted upon the outwardly bent spindle portion 17 at the lower end of said crank portion. The crank portion of the axle of the land side wheel. B is designated 19 and said land side wheel. is mounted upon the outwardly bent spindle '20 at the lower end of said crank portion. The rear furrow wheel C is 1nount ed to rotate upon the lower laterally extending end 21 of a crank axle having a vertical portion 22 which is mounted to rotate in a bearing 23 carried by a bearing member 2 1 pivoted upon a horizontal axis at 25 to sustaining plates 26, 26 securely fastened to the rear end of the adjacent beam 10.

The journaled portions ll and 18 of the axles of the wheels, A and B, respectively,

are provided with arms or cranks 5a and 57 which form elements of connections through which power applied to one of the rides to swing the crank portions of the latter may be transmitted to the other. The connections include a slidable member having a sea" mental toothed forward cud 56. The crank 54 has its upper end pirotally conneicted to the rear end (if-said slidablc member. at 54.

The connections also include a link 58 whose rear end is pivotally attached to the upper end of the crank 57 and whose forward end is pivotally attached to a lever 59. The lower end of the lever 59 is pivoted, at 59", to the forward end of the slidable member 55. This lever 59 is provided with a latch 60 having an operating element (10 which, in the embodiment illustrated, is intended to extend to within convenient reach of the op erator on the tractor. It should be here mentioned that the particular illustrated embodiment of the invention a tillage implement of the kind intended to be drawn by a tractor. 61 designates a longijitudinallv movable member which forms an element of the connection to the rear furrow wheel, C.

The forward end of this member 61 is pivoted at 61" to the sliding member Its rear end has connection with the rear furrow wheel through the medium of elements of any nature suitable to cause relative up and down movement of the rear end of the frame and rear furrow wheel C when the sliding member is moved in one direction and the other, respectively. The said sliding member is guided in its movement longitudinally of the frame by guiding elements 55 and 55" attached to the frame and sliding member, respectively. Springs and 81, whose rear ends are connected, respectively, to the cranks 54 and 57 and whose forward ends are connected to fixed parts of the implement frair balance the weight of the implement and thereby reduce the force required to be expended in the raising of the parts.

It will be understood that when the lever 59 is latched to the sliding member 55 rotatire movementof either journaled portion Ill or 18 of the axles will be transmitted to the other and will also cause longitui'linal more meat to be given the member 61. For er:- ample, if power he applied. to the c an]: portion 16 of the axle of the furrow wheel A to swing said crank portion forward or backward with relation to the frame, the arm or crank 54 projecting from the journaled portion of said axle will move correspondingly and since this arm or crank is connected to the slidable member 55, the latter will be 'correspondingly moved and will impart like movement to the lever which is latched to said sliding i11(I-1Tll)l and this lever will, through the link 58, apply power to the arm or crank 57 on the journaled portion 18 of the crank axle carried by the land wheel B. Movement of the sliding member 59will impart corresponding movement to the link 61 and this in turn will cause corresponding movement to be imparted to the rear furrow wheel C. i

On the other hand. itwill be apparent that when the lever 59 is not latched to the sliding member 55, rotative movement imparted to either journaled portion 14 or 18 of the crank axles will not be transmitted to the other or have any effect on the rear furrow wheel. For instance, when the lever 59 is unlatched from the sliding member, it may be moved back and forth relatively to said member and when so moved, it will correspondingly swing the crank portion 19 of the land wheel axle without efiecting corresponding movements of either furrow wheel A or C.

Further, it will be apparent that the wheels A, B and C are capable of back and forth movement relatively to the frame upon horizontal axes and that such movement may be transmitted to said wheels simultaneously and will raise the frame and ground working elements from working position to transport position and will lower said frame and ground working elements from transport position to working position, according to the direction of such movement of the wheels.

In this exemplificat-ion of the invention simultaneous movement of all of the wheels is primarily for the purpose of moving the ground working elements from and into transport position, and is eifected by power derived from the rotation of one of the sup porting Wheels (the forward furrow wheel A in this particular instance), through the medium of a power lift mechanism of suitable construction. Provision, however should be made for an adjustment of the ground working element or elements to variably determine the dept-h of penetration thereof into the soil when in working position, and provision should also be made for the leveling of the frame in every position of adjustment of the ground Working elements. It will be apparent that the pivotal adjustment of the lever 59 relatively to the sliding iug on the frame forward or backward, as

the case may be, without transmitting movement to the axle of the furrow wheel A, the sliding member remaining stationary during this movement.

he power lift mechanism which I prefer to employ is shown, described and claimed in my parent application. which has issued as Patent No. 1,606,132, hereinbefore referred to, to which reference may be had for a full understanding as to the details thereof. Suflice it to say in the present application, that it comprises a clutch having a driving member 27 and a driven member 28, the driving memher being suitably attached to the wheel A and the driven member rotativc upon the spindle portion 17 of the crank axle upon which said wheel A is loosely mounted. The clutch also comprises suitablemeans by which the driven member may be attached to the driving member under control of the operator nism includes an eccentric '45 which is attached to the driven member of the clutch and has rotative movement within an eccentric strap 46 provided with an arm47 whose upper end is pivoted at 47 to a lever 50; This lever 50 is pivoted at 50 to a fixed part of the frame and is provided witha latch, indicated at 52, by which it may be fixed in anyone of a number of selected positions to a tooth quadrant 53 suitably secured to the frame. The latch 52 in practice is as usual provided with a suitable operating member, which in the tractor drawn plow extendsto within convenient reach of the operator onthetractor. The adj ustment of thelever varies the angle to which the crank portion 16 of the axle of the furrow wheel A is set with referenceto the frame and ground. It will be noted that in this adjustment the eccentric 45, strap 46 and arm 47 move as a unit about the axis 50* and that the axle swings in its bearing in the frame, the direction of its swinging movement being forward or rearward according to the direction of movement given the lever 50. During this operation the clutch members are disengaged from each other and thewheel A runs free on theaxle spindle 17. But in the opera tion of raisingor lowering the implement by power derived from the forward travel of the implement the lever 50 substantially forms a fixed part of the frame, the eccentric 45 ro-- tates with the wheel A and within the eccentric strap 46 and said strap and arm turn upon the pivot 47?. It will be understood that the higlrpart of the eccentric 45 will be upward when the parts are in transport position and downward when they are in working position and that during the travel of the eccentric from one position to the other force will be exerted upon the axle spindle 17 to turn the axle portion 1a in its hearings in the main frame--the arm 47 and strap 46 in this movementswinging about the pivot 47 as already stated. Assuming that at this timethe lever 59 is latched to the sliding member 55, it will be apparent from what has already been i and will remain attached to said driving;

stated that all of the wheels will be moved simultaneously toward the front or toward the rear of the frame, as the case may be, when power is thus applied to the axle of the wheel A, thereby raising or lowering the frame and ground working element or elements carried by the frame.

It will be noted that any movement given the lever 50, whether by hand or by power dcrived from the travel of the implement, will be operative to swing the crank axle to which said lever is connected in its bearings upon the frame and thereby to move the corresponding wheel backward or forward. It will be apparent from what has already been stated that while the present embodiment of the invention contemplates that the hand move ment given the lever shall be merely for adjustment purposes, power lift means being provided to raise and lower the frame and ground working members when they have been thus adjusted, yet the invention in its broader aspects not confined to the utilization of power lift mechanism. It will also be apparent that any movement given the lever either by hand. or by the power lift mechanism will be transmitted not only to the crank portion 16 of the axle of the wheel A but to the corresponding portions of the axles of the wheels B and C when the lever 59 is attached to the slide 55, and will not be transmitted to the axle of either of said wheels B or C when the lever 59 is not secured to said sliding member 55. Again, it will be remembered that when the lever 59 is detached from the sliding member 55, it may be operative to swing the wheel B back or forth relatively to the frame without the transmission of corresponding movement to either of the other wheels. There are thus provided facilities not only for the raising and loweringof the. frame bodily from and into transport position but also for an adjustment of either side of the frame relatively to the other, through the medium of mechanism of simple and very practicable nature, whether applied to an implement having a power lift mechanism or to an implement in which the various adjustments and the movement bodily of the frame are accomplished wholly by hand or in part by hand and in part by a power lift mechanism.

Reverting now to the member 61 which has been referred to as a member w iich controls the relative movements of the rear end of the frame and the rear furrow wheel: it has been stated that the connection of the rear end between said member and the rear furrow wheel may be of any suitable kind. It may be here stated that the connection referred to preferably that illustrated in my aforesaid patent since it has important advantages, particularly in the type of tractor drawn implement il ustrated by way of example in the instant application.

Having thus described a preferred embodiment of my invention. and described the same somewhat minutely without intending thereby to restrict the protection to the particular illustrated embodiment but being mindful at all times and wishing it to be clearly understood that the embodiment is merely exemplary and that changes in details may be made without departing from the spirit of the invention what I claim is 1.
